The most grug brain way of achieving this (also the least efficient) would be to ask for more data than you're actually interested in.
Another way is to publish the entire dataset and make it query-able from different sources.
Need to think if I can come up with a non-grug method.
A recurring problem when thinking about ux in nostr is “I only want on friends to be able to see this” which nostr doesn’t really support very well. Could ask all your friends to auth with a private relay but you can’t just keep doing this every time someone wants this behavior.
“Private blinded networks” would really help here.
